Sleep Studies

Getting to the root of your sleep problems may require an at-home sleep study or spending a night at the Gundersen Sleep Center for an in-lab sleep study, or polysomnogram (PSG).

At-home sleep studies

Home sleep testing provides our experts with the information they need to diagnose your sleep disorder. In the comfort of your own home, we can learn more about how you breathe and measure your blood oxygen level and heart rate during sleep. You will have to wear special testing equipment, but you are usually able to set it up on your own.

A physician may recommend at-home sleep testing if:

  • It is likely that you have moderate to severe obstructive sleep apnea
  • The suspected obstructive sleep apnea is your only significant medical condition

You should not have at-home sleep testing if:

  • You are not at a high risk of obstructive sleep apnea
  • Your physician suspects you may be suffering from another sleep disorder
  • You suffer from medical conditions such as pulmonary diseases, neuromuscular diseases or congestive heart failure

If an at-home sleep test is not for you, your physician may recommend an in-lab sleep study.

In-lab sleep studies

Our in-lab sleep studies allow for the most complete evaluation of your sleep. During your overnight stay at the Sleep Center, our sleep specialists will monitor your sleep patterns through a comprehensive evaluation. While sleeping, a technician monitors:

Sleep study room
  • Brain waves
  • Eye movements
  • Muscle tone
  • Limb movements
  • Heart activity
  • Oxygen level
  • Air exchange

Some patients may also be asked to stay for a multiple sleep latency test (MSLT). The MSLT is a series of opportunities to nap during the day while your body functions are measured.

Is a sleep study for me?

The Sleep Center’s professional staff uses the results of your sleep study to diagnose sleep disorders and recommend appropriate treatment. If you think you may suffer from a sleep disorder, you can refer yourself to the Sleep Center, or you may be referred by a doctor. If you are referred by a doctor, he or she will receive a report on the sleep study results and recommendations for treatment.

Recommended treatment plans depend on the type and severity of the sleep disorder. Some conditions are treated with medications, while others may require a carefully planned change in sleep schedule. Surgery is occasionally advised to relieve severe breathing problems during sleep.
